The paper presents an empirical study conducted in the context of an advanced power electronics design course in a technical mursteinsformer university.In selected points of the lectures formative assessments were introduced and supported by the use of clickers.The purpose of the article is to examine students’ perceptions of the effectivene
Ultra-intense lasers produce and manipulate plasmas, allowing to locally generate extremely high static and electromagnetic fields.This study presents a concept of an ultra-intense optical tweezer, where two counter-propagating circularly polarized intense lasers of different frequencies collide on fender two tone amp a nano-foil.Interfering inside
We review two well-known definitions present in the literature, which are used to define the heat or energy flux in one dimensional chains.One definition equates the energy variation per particle to a discretized flux difference, which we here show it also corresponds to the flux of energy in the zero wavenumber limit in Fourier space, concurrently
